A headline at lefty smear site DeSmog:
Two funders of Lord Lawson's climate denial charity linked to energy industry.
The funders concerned are Lord Cavendish and Bryan Bateman. Their energy industry links are detailed later in the article. Lord Cavendish:
...recalls being the first person in Britain to build wind farms.
while Bateman is
a former engineer working on nuclear power stations.
So those links are to the low-carbon energy industry then.
